Commissioner of Taxation of the Commonwealth of Australia v 4 Doonan Street Collinsville Pty Ltd (in liq)

The Commissioner of Taxation (the Commissioner) appealed to the Court of Appeal of the Supreme Court of New South Wales against a decision concerning the application of a credit in a company's Running Balance Account (RBA) after the company had been placed into liquidation. The dispute arose when the Commissioner, after the company filed an amended assessment resulting in a credit in its RBA, set off this credit against other outstanding tax liabilities of the company in separate accounts. The company, 4 Doonan Street Collinsville Pty Ltd (in liq), contended that this set-off was impermissible.

The central legal issues before the Court of Appeal were whether the Commissioner was empowered or required to offset the credit entered in the company's RBA against outstanding debts in separate tax accounts, and whether this approach was inconsistent with the *pari passu* principle of distribution in liquidation. These questions engaged the interpretation of provisions within the *Corporations Act 2001* (Cth), specifically ss 500, 501, 553, and 555, as well as the operation of Part IIB of the *Tax Administration Act 1953* (Cth) concerning Running Balance Accounts.

The Court of Appeal allowed the Commissioner's appeal, setting aside the earlier orders of the primary court. The Court reasoned that the Commissioner's statutory powers and the nature of the RBA system permitted the set-off. The Court found that the RBA operated as a single notional account for the purpose of calculating a taxpayer's overall tax liability, and that a credit within this system could be applied against any outstanding debt within the same system, irrespective of whether those debts related to different tax types or periods. This approach was not considered to be contrary to the *pari passu* principle, which applies to the distribution of a company's assets among its creditors, not to the internal reconciliation of tax liabilities by the Commissioner. Consequently, the proceedings were dismissed.
